The RAAF Washington Flying Unit was a temporary Royal Australian Air Force unit formed to ferry Australia's first twelve F-111 aircraft from the United States to Australia upon their delivery to Australia. The unit was formed at McClellan Air Force Base, California on 31 March 1973 and was disbanded at RAAF Base Amberley, Queensland on 26 July 1973 after all twelve aircraft had safely reached Australia.
Despite the unit's name, the Washington Flying Unit was not the RAAF unit which was responsible for operating two Washington B.1 (B-29 Superfortress) heavy bombers in the early 1950s. These aircraft were operated by the RAAF's Aeronautical Research and Development Unit.
